usual open or light-emitting end is bridged j f' by av closure member, and this member is f I formed with an aperture covered by a' hinged y shutter. The shutter in turn has an aperture in which is mounted a lens, and at the incident side of the lens is provided a light filter preferably Y "f V character of daylight to the emitted rays and` thus remove ythe disadvantages' of artificialv light. Theswitch for controlling the lamp within the shade is conveniently mount- .ed in the closure member. Y

V'Iheinven'tion is fully'disclosed by way of description and in the accompanying drawing, in which Figure 1 is a `perspective view of a lampy eopiippedv with a shadek according to the inf 25' vention;

Reference to these views lwill now be made i f 30 byuselof1 like characters which are employed to" designate corresponding parts throughbut( a Y In Figure 1` is illustrated a lamp base 1 and a pedestal 2, thelatter having at its upper end 35, a head 3 which supports a lamp yshade in any desired manner. .This part of the construction is conventional and constitutes no part of the invention.V i

' The lamp shade is built on a frame which the former being larger than the latter and having a central lower end 7 ,of the 'bracket3 previously mentioned. A yconductor 8 passes through the end7 and into the shade as clearly shown in Figure 3. The frame is completed by a series Y of ribsQeXtendingv between the ringsv 4' and 5 rand thus assumes a pyramidal formation.

The mainenclosure of the frame consists of a shade 12 of suitable material and designsurrounding the ribs 9 and'having its upper end'extended asy l n at 13 across the upper ring 4 and secured to a smaller ring14 held within the ring 4. VThe lower end ofthe matcrial`12 iscarriedfupv'wardly and within the lower memberY and dicated .by the `numeraly 15. .f i

Qlhe shutterV in turn has azcentral yopenterl in'such a v,manner as to normallyv hold the ing,27.,inwhich ismounted a .condensing lens 28.1;On thef incident or flat side'of thek lens is-.laid alight filter 29 held in'positionby means ofv clips '30 and consisting. preferably y of afflat disk of glass of a bluish tint. 1 o 2 Across thewires 17- is'supported an up# a lampl socket 32 carrying a lamp 33.' The. latter preferably lies directlyyover the lens asclearly shown in IFigures 2 and 3. The conductor 8 leads t the' socket after passing through l closuremember 11. VThe shutter has a knobV i standing bracket. 31which in turn supports a screw switch 34V mounted in the 35 by means ofjwhich it maybe drawn yopen f to lpermit access tol the interior ofthe lamp shade Jfor the purpose of changing thel lamp.

' In the use of thedevice, with the lamp lighted, the filter 29 removes those rays which p are injurious to the eyes. When a filter of Y blue tint is used, as preferred, thelight is imparted the appearance and quality-of daylight, and in this respect'is far superior to ordinary artificial light. VVThe intensity of the light is 'reduced in the filtering process but is restored by means of the lens 28 which concentrates the rays into the Vuseful area.'

The lamp is conveniently turnedvoff and onV9 by means of the screw switch 34.

Although a specific embodiment of the invention has been illustrated and described, it will be 'understood that various alterations in the details of construction may be made without departing from the scope of the appended claims.

What I claim is :k

l. In a lamp shade, a closure memberin the light-emitting end thereof,"said closure having an aperture, a shutter hinged to said closure member and adapted to cover said aperture, and a lens in said shutter.

2. In a lamp shade, a closure member `in the light-emitting end thereof, said closure having an aperture, a shutter hinged to said closure memberV and adapted to cover said aperture, a lens in said shutter, and a light filter on the incident side of said lens.

Y 3. In a lamp shade, a closure member in `the light-emitting end'thereof, said closure having an aperture, a shutter hinged to said closure member and adapted to cover said aperture, alens in said shutter, a lamp socket supported in said shade, and a switch mounted in said closure member and electrically connected to said socket. Y 4c. In a lamp shade, an auxiliary frame supi ported in thelight-emitting end thereof, a closure member held by said frame, said cl'osure having an aperture, a shutter hinged to said closure member and adapted to cover said aperture, and a lens in said shutter.

5. In a lamp shade, an auxiliary frame supported `,in-the light-emitting end thereof, 'a closure member held by said frame, saidclosure having an aperture, a shutter hinged to said closure member and adapted :to cover Y V V said aperture, a lens in said shutter, .a lamp socket supported on said auxiliary frame,

and a switch mounted in'said closure member and electrically connected to said socket.

6. Ina iamp shade, a closure member fitted in the light-emitting end thereof and'spa'ced inwardly from said end, said shade being turned inwardly at said end to engage said member, and a lens mounted in said member.

In testimony whereof I afx my signature.
